Add uploaded file size to extracted data

[MikeSorokin]

https://github.com/mscdex/busboy#examples show how to extract data:

busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
  console.log('File [' + fieldname + ']: filename: ' + filename + ', encoding: ' + encoding + ', mimetype: ' + mimetype);
  file.on('data', function(data) {
    console.log('File [' + fieldname + '] got ' + data.length + ' bytes'); // <-- HERE
  });
  file.on('end', function() {
    console.log('File [' + fieldname + '] Finished');
  });
});

Is it possible to implement this feature in this package?

Hi @dominhhai ! Any feedback would be useful...

Hi @MikeSorokin
Sorry for late response. It is not possible to implement this.
PR are always welcome!

@dominhhai late response is better than no response at all :) Can you explain why implementation is not possible? Reasons may be too obvious for me to see them by myself...
